Vicor Corporation unveils 12V to 48V converter at GTC 2018.

Vicor Corporation announced a 12V to 48V non-isolated up converter to support 48V high-performance GPUs in data centers that are still relying on legacy 12V power distribution. The 2317 NBM converts 12V to 48V with over 98% peak efficiency, 750W continuous and 1kW peak power in a 23 x 17 x 7.4mm surface-mount SM-ChiP package. The NBM provides a complete solution with no external input filter or bulk capacitors required. By switching at 2MHz with ZVS and ZCS, the NBM provides low output impedance and MHz fast transient response to dynamic loads. The NBM incorporates hot-swap and inrush current limiting. The NBM supports state-of-the-art 48V input GPUs using Power-on-PackageModular Current Multipliers ("MCMs") driven from a 48V node sourcing a small fraction (1/48) of the GPU current. Current multiplication overcomes the power delivery boundaries imposed by traditional 12V systems standing in the way of higher bandwidth and connectivity.
